Gutter Covers
Moline, Illinois

Never clean your gutters again with our covers from GutterRoof and GutterRx™ in Moline, IL. At Mainstream Home Improvement, our metal gutter covers are shaped to protect your system from clogging with leaves and causing potential water damage over time. These protection systems direct flowing water towards the nose portion of the gutter where it falls into the trough and releases into your city drainage system. Not only are our gutter covers an attractive option for your roof, but they last longer than the average aluminum system. Forget spending hours digging wet leaves out of your gutters, simply let the wind take them away and avoid the hassle year after year. To learn more about our gutter covers, contact us today.

Our office manager has years of experience with our roofing, windows, patio doors, and siding services to give you all the information you need to schedule an initial inspection!

What are some of the most common pricing games that typical window places want to play?

Pricing games are when a contractor gives you an extremely low price on their services to entice you to invest in their company. This allows them to give you what you paid for – which oftentimes is lower quality for half the cost and guaranteed future issues. To make sure that you get expert service for an affordable price, our team at Mainstream Home Improvement guarantees to provide you with honest quotes that always show the exact price, and absolutely no pricing games along the way.

You guys have a lot of glowing reviews. Why can’t I find customer reviews on other companies’ websites?

While we’d like to think it’s because of our passion for customer service, we know that there are plenty of home improvement companies out there that provide the same care. However, we believe that our reviews simply come from our experience and wide range of services. Our contractors are dedicated to providing perfectly completed roofing, siding, window, patio door, & gutter services to homes throughout Moline, IL. Our office managers also make sure that all your questions are handled before, during, and after your project for a truly smooth project experience.

Why do you only have production managers or owners on the final walk through?

Before we let homeowners see their newly finished project, our project managers love to give a final walkthrough beforehand to make sure everything is flawless. We always say, it’s better to have more than a few sets of eyes looking over an installation or repair – most of the time if something needs to be altered, our project managers will catch it in that final inspection. This is just another way to ensure that your project is completed perfectly to ensure your 100% satisfaction.
